From Article IV of the Illinois Constitution....

SECTION 14. IMPEACHMENT
    The House of Representatives has the sole power to
conduct legislative investigations to determine the existence
of cause for impeachment and, by the vote of a majority of
the members elected, to impeach Executive and Judicial
officers. Impeachments shall be tried by the Senate. When
sitting for that purpose, Senators shall be upon oath, or
affirmation, to do justice according to law. If the Governor
is tried, the Chief Justice of the Supreme Court shall
preside. No person shall be convicted without the concurrence
of two-thirds of the Senators elected. Judgment shall not
extend beyond removal from office and disqualification to
hold any public office of this State. An impeached officer,
whether convicted or acquitted, shall be liable to
prosecution, trial, judgment and punishment according to law.

KEEP IN MIND FOLKS, THIS IS NOT A COURT OF LAW.

From Article V of the Illinois Constitution..........

SECTION 6. GUBERNATORIAL SUCCESSION
    (a)  In the event of a vacancy, the order of succession
to the office of Governor or to the position of Acting
Governor shall be the Lieutenant Governor, the elected
Attorney General, the elected Secretary of State, and then as
provided by law.
    (b)  If the Governor is unable to serve because of death,
conviction on impeachment, failure to qualify, resignation or
other disability, the office of Governor shall be filled by
the officer next in line of succession for the remainder of
the term or until the disability is removed.
    (c)  Whenever the Governor determines that he may be
seriously impeded in the exercise of his powers, he shall so
notify the Secretary of State and the officer next in line of
succession. The latter shall thereafter become Acting
Governor with the duties and powers of Governor. When the
Governor is prepared to resume office, he shall do so by
notifying the Secretary of State and the Acting Governor.
    (d)  The General Assembly by law shall specify by whom
and by what procedures the ability of the Governor to serve
or to resume office may be questioned and determined. The
Supreme Court shall have original and exclusive jurisdiction
to review such a law and any such determination and, in the
absence of such a law, shall make the determination under
such rules as it may adopt.

As we always tell you....do your own research.  Don't rely on the media or lawmakers to tell you which way is up or down.  And certainly, don't let anyone tell you "You just don't understand."

Blago remains governor until one of three things happen....he resigns (not likely...he'll probably end up barricading himself in his home or office)....he is unable to carry out his duties (physically/mentally incapacitated)....or he is IMPEACHED.
